lO WHOM IT MAY CONCERN:

Be it known that I, Luorcn Floor, of Hoboken, in the county of Hudson,and Stnteof New J ersoy, hovel invented certain new and usefulimprovemcnts'in Inflnting India-Rubber Bulls and other Articles; andIheroby' declare the following to be it full, clear, and exactdescription of the snm e,'rcfcrcnoo being had to the aceompnnyingdrawings, in which-- Figure 1 is a. perspective view of u ball with my.improvements applied; and Figure 2 is a vertical central section of thesome.

The chief objection to the hollow rubber bulls and other similnrarticles now in the. market, is thnt there ore no menus provide-.1 forugnin inflating them after the air they contninhas escnpcd or becomepnrtiallyexhausted, or for other rensons is insuificient to disteml themproperly. In the majority'of instances, after being used for a. littletime, they become relaxed and comparativelyinelasticeud flaccid so as tobe unfitted for the purposes for which they are designed. Anotherdrawback to their use is that they nrc manufactured an inflated state,and necessarily occupy a great deal of room when packed fortransportction that might be saved by making them capable of beingcollnpsedor compressed when not in us'c. 7

The object of my invention is to obviate these objections, and provide areodyn-nd simple means whereby India rubber balls, pessurics, and othersimilar articles may be muintninedin an inflated and distended state aslong us desired, and :itthe some time rendered collnpsnble, so as to becompressed and packed into a small space when not in use; and tothis-end my invention consists in the application to a. hollow bull, orothcr article requiring to be distended by inflation, of u. flexible andelastic niwtube arranged in such manner thutby bending over andinserting its top or end into a recess formed in the ball around thebase of the tube, the opening in the tube shall be closed and the oilvWithin the ball prevented from escaping. The tube may be forced downinto the cup or recess until it is flush with the exterior surface ofthe bull or other orticle, end it can be readily removed from the recesswhenever it is desired to discharge the compressed air from the bull, Itwill of course be undcrsreodthat although in the specification, and inthe diawings which nccompnny it, I have illustrated my invention by it'snpplicntiou to a common India-rubber ball, I by no menus limit myselftothntperticulnr applicntion, but contemplate using it in my connection inwhich it mny he required, as, for instance, with lifepresorvers,pessaries, &c. In fig. 2 of the drawings, the method of securingundoperating the tube is fully shown. The base of the tube a is attached tothe bottom of the recess or cup 1), formed in the ball 0, by anysuitable moons. The tube extends upwards, and is closely surrounded bythe sides of the recess, which being formed of rubber or other elasticsubstance, are capable ofexpcnding or stretching when occasion demands.The position of the tube when erect and open is shown in red lines theball relaxed and collapsed is also repre sentcd in redlines. Now, whenit is required to inlluto the balhnir is forced through the tube untilthe ballia completely filled and distended. The tube is then compressedbetween the thumb and one of the fingers, so as to prevent the escape ofthe nir, and its top bent over ou'd inserted in the cup or recess.between the sides of' which and the besoof the tube it is tightlycompressed, so as to hermetically close all communication between theinterior of the bull and the outside air. The tube in this position isshown in. black lines in figs. 1 and 2,

where it is represented as projecting ubove the surface of the bull. Itcan be readily forced down, howevcr,

until it is flush with the surface. When itis desired to discharge theair from the bull, the end of the tube is drown out from the recess 6,thus giving egress to the air. The ball may now be compressed, so as tooccupy vcrylittle space, a feature which renders its transportation easyand inexpensive, there being but little bulk or weight, It will thus beseen that by means of this simple device I nm enabled to readilyinflo'te or compress,

the bull or other articles us above specified, or keep it constantlydistended to its fullest capacity.

Having described my invention, and the manner in which the some isor'muy be cnrr-ifoil into-effect, whet I claim, and desire to secure byLetters Patent; is-

The application, to an linlio-rubber bull or other hollow articlerequired to be distended by inflation, of a. flexible tube, in themanner substnntinlly as herein specified, so that the scid bull orothclarticle may be either inflated and distended, or collapsed, as andfor the purposes set forth.

In testimony whereof I have signed my name to this specification beforetwo subscribing witnesses. I
